14 Inches High Tilting Torque Slew Ring Drive With AC Motor For Construction Machinery
Slew Ring Drive Description
A: Bearing inner ring+ball+bearing outer ring = BEARING
B: worm+wormwheel = Worm and wormwheel structure
If adding gear to the outer ring of the bearing, then A and B become a slew drive.
Maintain advantages: large torque, good sealing, high bearing force of the end cover.
It can be matched with AC motor, DC motor, synchronous motor, brushless motor. There are also other motors could be matched, no matter what motors we choose, basically we need to look at some parameters: 1. Rated power/torque during normal operation 2. Normal power/ torque during a stable state; 3. Tracking accuracy; 4. adapt to temperature environment; 5.IP grade, waterproof, dustproof; 6. Economic reference; 7. service life; 8. Tracking speed, etc.
Why tracking systems?
Because of sunrise and sunset…
Wrong – the sun doesn’t rise and set.
But it appears to rise and set because of the Earth’s rotation on its axis.
So solar trackers are counteracting Earth’s rotation.

Applications
Portal cranes for port handling and hydropower station
construction, towers for building construction
Cranes and general inland port cranes, etc.
Jib type mobile slewing cranes, such as automobile type, tire type,
crawler type, railway type, floating type, etc.
In overhead cranes with slewing jib or slewing device trolley. It
is mainly used under special conditions that require the expansion
of the working range beyond the span of the bridge crane or to meet
certain technological requirements. Such as: metallurgical cranes
for charging cranes in open hearth furnaces, clamp cranes for
soaking furnaces in blooming mills, rake cranes for billet
warehouses, etc., all equipped with slewing mechanisms.
